Active Shape Models with Stasm

Stasm is a C++ software library for finding features in faces.
You give it an image of a face and it returns the positions of the facial features.
Stasm is based on the Active Shape Model of Tim Cootes and his colleagues.

Stasm is designed to work on front views of faces with neutral expressions.
It performed very well in an independent 2013
comparative study.
